When the trainee does pull-ups, the muscle electrical signal sensor will detect the electrical activity signal of the muscle. By analyzing these signals, the order and intensity of muscle contraction can be determined to monitor whether the trainee starts the pull-up according to the correct movement pattern.

[0019] The present invention provides a waist protection mechanism. When the connecting column moves upward, it squeezes the elastic frame. When the elastic frame is squeezed, the middle part of the elastic frame will bend. When the middle part of the elastic frame bends, it pushes the driven frame to move in a direction close to each other. When the driven frame moves, it drives the sliding frame to slide on the inner wall of the slide plate in a direction close to each other. When the sliding frame slides, it drives the driven rod to move in a direction close to each other. When the driven rod moves, it pushes the push plate to move in a direction close to each other. When the push plate moves, it pushes the telescopic plate to move forward and fit with the waist of the trainee. When the telescopic plate moves, the pulling force of the pulling plate causes the two ends of the telescopic plate to shrink. When the telescopic plate contracts, it will drive the buffer elastic rod to move towards each other. When the buffer elastic rod moves, it will push the contact rubber pad to move towards each other and fit with both sides of the trainee's waist, thereby preventing the trainee from spraining the waist when dangerous movements occur while doing pull-ups. When the trainee does pull-ups, the joint angle sensor will be used to measure the angle change of the shoulder joint in real time, and combined with the muscle electrical signal, it can be determined whether the shoulder movement is within the normal range. When the angle change is abnormal and the muscle contraction pattern is wrong, it can be determined as an incorrect force application method. For example, premature locking of the shoulder will cause the angle change to not conform to the normal pull-up trajectory.

[0020] The present invention provides a correction mechanism, when the driven frame moves, it will drive the U-shaped plate to move in the direction of approaching each other, when the U-shaped plate moves, it will push the right-angle frame to move in the direction of approaching each other, when the right-angle frame moves, it will pull the resetting elastic rod to extend in the direction of approaching each other, when the U-shaped plate moves, it will drive the vertical rod to move in the direction of approaching each other, when the vertical rod moves, it will squeeze the elastic plate, when the elastic plate is squeezed, the middle part will be bent, when the middle part of the elastic plate is bent, it will push the correction rod to move downward, when the correction rod moves downward, it will fit with the shoulder of the trainee, so as to detect whether the shoulder of the trainee is kept level when doing pull-ups, when the trainee does pull-ups, the pressure sensor can be used to sense the size and distribution of the grip of the trainee's hand on the horizontal bar, different grip patterns can also reflect the trainee's force tendency to a certain extent, and assist in judging whether the force is correct, and when the microprocessor determines that the trainee has made a mistake in exerting force, such as premature over-contraction of the shoulder muscles, the vibration ring will vibrate to remind the trainee to adjust the force mode. The intensity and frequency of the vibration can be adjusted according to the severity of the error so that the trainee can clearly perceive the prompt information.
